Why Upgrade Your Fuel Rail?

A high-performance fuel rail ensures your engine gets the fuel it needs under all conditions.

Benefits of an Upgraded Fuel Rail:

• Increased fuel flow capacity
• Stable fuel pressure under load
• Improved engine performance
• Supports turbo and high-HP builds
• Better tuning control

Superb Performance: 1/2 inch fuel hole can enhance fuel glide as much as 1000 horsepower. 1 / 8th NPT port is included to accommodate nitrite settings or fuel pressure gauges

Why This Kit Stands Out

Unlike basic fuel rails, this kit includes everything needed to upgrade your fuel system:

• Fuel Rail → Increased flow capacity
• Fuel Pressure Regulator → Adjustable pressure for tuning
• Gauge → Real-time pressure monitoring

This combination allows for precise fuel control and safer high-performance operation.

Complete Hardware & Fittings: Package includes: B series fuel rail + FPR008 fuel valve + FF1007 AN6 filter + one AN6 connector + one without standard fuel gauge + one pipe

Ideal For:

• B-series swapped Civics and Integras
• Turbocharged builds
• High-horsepower naturally aspirated setups
• Track and race applications
• Performance tuning projects

Vehicle Fitment: For Acura/Honda Integra Civic Del Sol Si B16A B16A1 B16A2 B16A3 B18C B18C1 B18C5 B20B B20Z

Installation Notes

• Requires proper fuel line routing
• Ensure injector compatibility
• Adjust fuel pressure according to your setup
• Professional installation and tuning recommended

Performance Benefits

Installing this fuel rail kit can:

• Improve fuel delivery consistency
• Support higher horsepower levels
• Enhance tuning accuracy
• Reduce risk of lean conditions
